The issue affects all shipping versions of Magento Community Edition (CE) and Enterprise Edition (EE). Operating system Versions affected are:

  • CentOS 5.x and 6.x.
  • RedHat Enterprise Linux 5.x and 6.x.
DETERMINING YOUR VULNERABILITY TO THE FILE SYSTEM ATTACK: To confirm you are Vulnerable create a file named test.php.csv anywhere in your web server’s docroot with the following contents:
?php phpinfo()
Display that page in a web browser. (For example, http://www.example.com/path/test.php.csv If your browser saves the file or prompts you to save the file instead of displaying it, your server is not vulnerable.]]>
